How does water purification equipment work? After reading this article, you will understand! Do you know what's in the water you drink every day? In addition to water, there are many other substances, some of which are beneficial, such as minerals and trace elements, while others are harmful, such as bacteria, heavy metals, pesticides, residual chlorine, etc. With the increasingly serious water pollution, is the water quality we drink safe? Introduction to the principle of water purification equipment: In order to ensure the safety and health of drinking water, many people choose to use water purification equipment to filter out harmful substances in water and provide purer drinking water. So, how does water purification equipment work?
This article will provide you with a detailed introduction to the working principle of water purification equipment, allowing you to understand the science and technology of water treatment. The main components of a water purification equipment are usually composed of the following parts: a pre filter, which is used to remove large particles of impurities such as sediment, rust, suspended solids, etc. from the water, and protect subsequent filters from blockage or damage. Ultrafiltration membrane: used to remove microorganisms, colloids, organic matter, etc. from water, with a filtration accuracy of 0.01 microns, and can intercept bacteria, viruses, etc. Reverse osmosis membrane: used to remove dissolved inorganic substances, heavy metals, pesticides, residual chlorine, etc. from water, with a filtration accuracy of 0.0001 microns. It can intercept calcium and magnesium ions, chlorides, nitrates, etc. Post filter: used to further improve the taste and hygiene of water quality, generally including the following types: activated carbon: used to remove odors, pigments, organic matter, etc. from water, increase dissolved oxygen in water, and improve water activity. Softening resin: used to remove hardness ions such as calcium, magnesium, etc. from water, prevent the formation of scale, and protect faucets, kettles, etc. Mineralization ball: used to increase the minerals and trace elements in water, such as potassium, sodium, calcium, magnesium, etc., balance the pH value of water, and improve the nutritional value of water. UV lamp: used to kill residual bacteria, viruses, etc. in water, ensure water hygiene and safety, and extend the shelf life of water.
The working principle of water purification equipment is mainly to use different physical, chemical or biological methods to remove harmful substances from water, improve the cleanliness and applicability of water quality. Let's take a look at several common filtration principles in water purification equipment. The filtration principle of ultrafiltration membrane is a pure physical filtration method, which is composed of one or more layers of thin film covered with micropores. The diameter of the micropores is generally around 0.01 microns, allowing only water molecules and some small molecules to pass through, while intercepting large molecules such as bacteria, colloids, organic matter, etc. The working principle of ultrafiltration membrane is to use the difference in water pressure to push water from the high-pressure side to the low-pressure side, thereby achieving the separation of water and impurities. The advantages of ultrafiltration membranes are that they do not require electricity, do not produce wastewater, and can retain minerals and trace elements in water. However, the disadvantage of ultrafiltration membranes is that they cannot remove heavy metals, chemical pollutants, and scale from water. The filtration principle of reverse osmosis membrane is an efficient filtration method, which is composed of one or more layers of semi permeable membranes. The characteristic of semi permeable membranes is that they only allow water molecules to pass through and intercept all other substances, including dissolved inorganic substances, heavy metals, pesticides, residual chlorine, etc. The filtration accuracy reaches 0.0001 microns, and can intercept calcium and magnesium ions, chlorides, nitrates, etc. The working principle of reverse osmosis membrane is to use the action of high-pressure pump to push water from the low concentration side to the high concentration side, thereby reversing the permeation phenomenon and achieving the separation of water and impurities. The advantage of reverse osmosis membrane is that it can remove the vast majority of pollutants in water and provide the purest drinking water. However, the disadvantage of reverse osmosis membranes is that they require electricity, generate wastewater, and also remove minerals and trace elements from the water.
Water purification equipment is a device that can improve water quality. Its working principle is mainly to use different physical, chemical, or biological methods to remove harmful substances from water and provide purer drinking water. The main components of water purification equipment include pre filters, ultrafiltration membranes, reverse osmosis membranes, post filters, etc. They each have their own advantages and disadvantages, and the appropriate combination needs to be selected according to water quality and demand.
